Where Is Tony Stewart?

That's the third Sprint Cup race he's skipped since his car struck and killed Kevin Ward Jr. during a sprint car race.

Stewart's decision will once again lead to Jeff Burton replacing him in the Number 14 Chevrolet. Burton also drove Stewart's car at Michigan last week.

Stewart has been in seclusion since the August 9 incident at an upstate New York dirt track that remains under investigation. Ontario County Sheriff Philip Povero has said investigators don't have any evidence at this point to support criminal intent by Stewart.
